Copyright © GENIVI Alliance 2020 11 11 Audio HAL Report 12 Android Automotive SIG – Audio HAL – Report • Main thread of work - How to Control a Car Audio System with Android Providing sources and sinks Controlling the complete System Audio Audio Source Audio Sink Source Audio Audio Audio Sink Source SourceAudio Audio Source Source sources streams / input stream raw streams raw streams input streams Audio Audio Source Source Audio Sink Audio Audio Source Audio Sink Source Audio Audio Source Source green and blue boxes can be partitions / virtual machines or different HW • Both strategies have advantages and disadvantages • Relying on Android only does not fulfill some safety requirements • Considering Android as sources and sinks only does not take enough advantage of it • Therefore each topic has to be analyzed and assigned : inside or outside Android 13 Android Automotive SIG – Audio HAL Proof Of Concept - Getting Raw Streams System Level Audio Manager OS Level Audio Manager Proxy System Level Audio Manager • Reference design from Google side by side to the GENIVI Proof Of Concept proposal • Android design relies on an External System (Mixer, Amplifier, Safety signals,…) • GENIVI Proof Of Concept tries to provide an concrete instantiation of the Audio Control Split 14 Android Automotive SIG – Audio HAL – Report • Team participants: BMW, Mobis, TietoEVRY, EPAM, Bosch, Analog Devices • Main thread of work - How to Control a Car Audio System with Android • proof-of-concept implementation in-progress - Getting raw streams out of Android • Demo was shown in the workshop • Source code repository https://github.com/GENIVI/android-external-audio-mixing • Topics discussed at the tech summit • Audio Manager integration (Android audio manager & GENIVI Audio Manager co-existence) • Proof-of-concept architecture & “prerequisites” : extracting raw streams, injecting input streams • Feature content definition for next milestone : • Utilization of actual hardware instead of Android emulator • Going through the list of prioritized topics for and refining the priorities with participants • Backlog update in progress 15 New project opportunities • Broadcast radio and Android • Location-based services and Android • How to plug alternate navigation engines 16 Thank you!
